OWC 5U2D51R8016P 16GB (2x8GB) DDR5 5200 CL42 1.1V 288-pin UDIMM kit for HP OMEN 40L 45L

System-Specific DDR5 Kit for HP OMEN 40L and 45L

This OWC kit supplies 16GB of DDR5 memory in a matched pair of 8GB modules. It is built for HP OMEN 40L GT21-2100t and 45L GT22-1000m, GT22-1470se and GT22-2000t desktops. The modules are unbuffered, non-ECC UDIMMs that run at the standard 1.1V.

Upgrading from Slower or Smaller Factory Memory

The kit replaces the original DDR5 DIMMs fitted by HP at 5200 MT/s with CL42 latency. The jump is worth it when the system shipped with less than 16GB total capacity or when the factory modules run at a lower JEDEC speed grade. The 1Rx8 organisation keeps electrical loading low on the memory controller.

Limits of the DDR5 5200 JEDEC Standard

The PC5-41600 rating sets the maximum data rate at 5200 MT/s and the timing at CL42 under JEDEC specifications. Voltage is fixed at 1.1V with no XMP or EXPO profiles available on these modules. Builders who need higher frequencies or tighter latencies must choose a different memory standard.
